Hi Dave,
Here are a few suggestions:
In the first 10 seconds your user shoud be able to figure out what you do.
I know that your headline (or maybe that's your logo) that says "Group Purchase Online," but I would take it a step further.
Add something to the header that really explains what yous site is all about.
Something like, "Save Money, Shop With Strangers. Yes, I said shop with stangers. Daily deals are available to everyone who buys before the countdown timer runs out (see the timer to the left, right, top or wherever it is in relation to this banner). What's the catch? We have to sell X widgets before this awesome price is available. So, check back often throughout the day (or we'll keep you posted via email, whatever your policy is) to let you know how it's going. At the end, if we've met the magic number, you'll receive a congratulations message." Ok, something like that.
The photos of the white furniture are a little difficult to see, perhaps ask your designer to ad drop shadow or adjust the saturation of the image.
Consider making the credit card logos smaller. Most people will assume that you accept credit cards because it is an online purchase.
What does the "find motivational" quotes on the left rail have to do with your buying service. Seems in incongruent with your brand.
In the Facebook like box, reduce the amount of faces shown. We don't really need to see all of those faces in such a narrow space. If someone is interested in your KLOUT they see the number of people who like you.
Consider adding more product images on both sides, or consider showing the last deal. So potential customers can see what a value they can receive.
Customers should see tweets from you on a daily basis in your Twitter feed. If you are going to post the same product, change your text. "Comfrotable .... " appears twice.
You have over 3,000 followers. That's great. Consider congratuling the winner on Twitter. At the check out process ask for their Twtter handle.
I wish you luck.
Best regards,
Wendy
P.S. Let me know if you like any of the suggestions.
